Installation Instructions

-Installed inside the panel

Fixed Type Installation:

The circuit breaker is securely mounted on the distribution cabinet or installation board and is immovable once installed.

Ideal for scenarios that do not require frequent switching or ongoing maintenance.

Easy installation and cost-effective setup.

Drawout type installation:

The circuit breaker is affixed on a withdrawable frame, allowing for effortless maintenance, testing, and replacement of components.

Perfect for environments that require regular operation or servicing.

Installation is intricate and incurs higher costs, but it provides enhanced adaptability.

Plug in type installation:

The circuit breaker connects seamlessly to the busbar via a plug-in mechanism, ensuring rapid installation and swift replacement.

This method is perfect for conditions that demand quick replacement.

-Secondary wiring method

1 and 2: Connect the intelligent controller seamlessly
27 and 28:Link the undervoltage coil efficiently
29 and 30: Securely attach the shunt coil
31 and 32:Anchor the closed coils firmly
34 and 35: Connect the energy storage motor reliably

Product testing

Mechanical operation test:

Check whether the mechanical operation of the circuit breaker is flexible and reliable.

Test the operation functions such as closing, opening, and energy storage.

Electrical performance testing:

Insulation resistance test: Use a megohmmeter to measure the insulation resistance of the main and auxiliary circuits, ensuring that they meet the standard (usually ≥ 1M Ω).

Power frequency withstand voltage test: Apply rated power frequency voltage (such as 2500V/1min) to the main circuit and auxiliary circuit to check the insulation performance.

Contact resistance test: Measure the contact resistance of the main contact to ensure that it is below the specified value (usually micro ohm level).

Protection function test:

Test the action values and time of protection functions such as overload, short circuit, and ground fault.

Verify the settings andfunctionality of the intelligent release device.

 

Packaging & Shipping

Outer packaging:

To ensure unparalleled protection and strength for our products, we utilize robust and durable wooden boxes that are specifically designed to provide exceptional mechanical strength, safeguarding your investment during transit.

Our wooden crates are perfectly suited for accommodating large circuit breakers or for resilient international transportation, ensuring your products arrive in pristine condition.
